Re: -90 on AP, -62 on Client
I think he was saying the trees would not be the REASON for the difference in signal readings. When you moved the CPE and picked up a signal on the CPE, the signal probably increased equally on both ends. It just turns out that the signal at the AP was not higher than the AP's sensitivity, so it showed no signal.
The reason for the difference would most likely be higher amplification at the AP end than at the CPE end, it is a pretty common problem.
Remember, amplification is one-way. All things being equal, if you have 30db output power at the AP, but only 23db output power at the CPE, then you would see 7db less signal at the AP (assuming equal antenna gains).
The easiest solution is to just use a higher gain antenna at either the AP or the CPE. Antenna gain is bi-directional and is typically preferred over increasing output power.
Having said that, -90 at the AP and -62 on the client is a big gap. What is the output power and antenna gain of the AP (and the CPE)?
